Title: Manufacture of electronic component
Inventor: YOSHINAGA TAKASHI
IPC: H01G13/00
Filed: 1988-09-08
Abstract: PURPOSE:To prevent deterioration in the electrode performance by laminating a surface electrode layer made of Ag on a background electrode layer made of Cu so as to form an electrode and using solder containing a Cu content so as to solder the electrode. CONSTITUTION:An electrode 3 is formed by laminating a surface electrode layer 2 made of Ag on a background electrode layer 1 made of Cu and the electrode 3 is soldered by using the solder 14 containing the Cu content. Thus, the Cu of the background electrode layer 1 is hardly diffused toward the solder 4 at the soldering and the soldering corrosion resistance of the background electrode layer 1 is improved, the soldering temperature rises excessively and even if soldering corrosion takes place in the surface electrode layer 3 made of Ag, no soldering corrosion is caused to the background electrode layer 1 made of Cu. Thus, the deterioration in the electrode performance is prevented.

Title: Optical disk input/output system
Inventor: MOROTA YOSHIZO
IPC: G11B7/004
Filed: 1986-09-26
Abstract: PURPOSE:To improve write efficiency by buffering write/read requests on a memory and permitting a read data size to coincide with a track size which is regulated by means of an optical disk. CONSTITUTION:A host system executes data-writing/reading on the optical disk system and uses an incorporated memory for a track buffer of when the optical disk is inputted and outputted. The host system copies the write request for a sector S1 in the track buffer, and as for a next sector S2, a sector (S-S1) is copied in the track buffer. Since the track buffer becomes full, said system writes the contents in the track T of the optical disk device. After one rotational delay, a DRAWN-processing is executed. After the track buffer is cleared, a remainder sector (S1+S2)-S is copied in the next track buffer. With the write request of a sector S3, writing is executed in a track T+1 if the track buffer is full, whereby write efficiency can be improved.

Abstract: PURPOSE:To prevent a punch-through from occurring at a notch part in case a junction is impressed with inverse voltage by a method wherein after diffusing impurity on a notch part and the periphery thereof of surface layer, conductive impurity is formed. CONSTITUTION:Before forming p (or n) type conductive impurity, n (or p) type impurity with relatively high concentration is diffused on a notch part Z and the periphery thereof of surface layer Y formed by epitaxial growing process and then p (or n) type conductive impurity is formed. Through these procedures, in case of p type emitter diffusion, such a part may not be inverted to p type causing no apparent abnormal diffusion of p type impurity. Resultantly even if a J2 junction is impressed with inverse voltage, no partial punch through is caused. Moreover, p type emitter diffusion is performed through the notch part of surface layer formed on an n<+> layer to shortcircuit the p type emitter layer with an N type base layer but no troubles may be caused at a reverse conductive thyristor and a gate.turn off thyristor since they do not require the withstand voltage at J1 junction at all.
